Nick and Tesla's High-Voltage Danger Lab: A kids' mystery novel with electromagnets, burglar alarms, and other gadgets you can build

Nick and Tesla are a couple of teenagers who get themselves into trouble and must build MAKE-style projects to save the day. There are two books in the series, aimed at ages 9-12, and they contain a number of fun DIY projects. The publisher, Quirk Books, kindly gave us permission to run a lengthy PDF excerpt from Nick and Tesla's High-Voltage Danger Lab that includes plans for making a compressed-air water rocket.
